Trying to get WEBDAV to work on Community Edition 201711 EA

I am trying to get WEBDAV to work on Community Edition 201711 EA. Specifically trying to map a drive on our Windows 2008 server to the WEBDAV location. The WEBDAV browser links work fine (both /webdav and /aos) but for the life of me I can't get the drive mapping in Windows 2008 to work. I've tried using the URL and the \\servername\share syntax with no success. Am I missing something else?
